LK-J11 The Endo Ultra Activator consists mainly of a high frequency oscillation circuit, which generates a high frequency oscillation signal to achieve ultrasonic vibration, thus causing the working tip to resonate and penetrate deep into the root canal, promoting ultrasonic flow and cavitation of the fluid inside the root canal to achieve better debris swishing and cleaning results. It comes with led light, and 6pcs autoclavable tips, which can be autoclave at a temperature of 134°C and a pressure of 0.20Mpa-0.23Mpa for 4min. The handpiece is cordless, and lithium battery-operated.
